我正在尝试使用X轴绘制时间和Y轴绘制内存绘制图形。我从大约5天的数据日志文件中解析此数据，我想按原样绘制所有数字。我对matplotlib相当陌生，因此无法弄清楚如何为xticks添加空间。我能够在24小时内生成图表，但是xticks非常混乱。
代码如下：
import datetime
import random
import matplotlib.pyplot as plt
from matplotlib.pyplot import figure
import numpy as np
x = ['11:26', '11:36', '11:43', '11:50', '11:58', '12:05', '12:13', '12:20', '12:27', '12:33', '12:38', '12:44', '12:49', '12:54', '12:59', '13:04', '13:10', '13:15', '13:21', '13:27', '13:33', '13:39', '13:46', '13:53', '14:00', '14:07', '14:15', '14:20', '14:35', '14:50', '15:05', '15:20', '15:35', '16:06', '16:15', '16:23', '16:30', '16:37', '16:45', '16:52', '16:59', '17:07', '17:13', '17:18', '17:23', '17:28', '17:34', '17:39', '17:44', '17:49', '17:55', '18:01', '18:07', '18:13', '18:19', '18:26', '18:33', '18:40', '18:47', '18:54', '18:59', '19:15', '19:30', '19:45', '20:00', '20:15', '20:46', '20:55', '21:03', '21:10', '21:17', '21:25', '21:32', '21:40', '21:47', '21:53', '21:58', '22:03', '22:09', '22:14', '22:19', '22:24', '22:29', '22:35', '22:41', '22:47', '22:53', '22:59', '23:06', '23:13', '23:20', '23:27', '23:34', '23:39', '23:55', '00:10', '00:25', '00:40', '00:55', '01:26', '01:35', '01:43', '01:50', '01:57', '02:05', '02:12', '02:19', '02:26', '02:33', '02:38', '02:43', '02:48', '02:53', '02:59', '03:04', '03:09', '03:15', '03:21', '03:27', '03:33', '03:39', '03:46', '03:53', '04:00', '04:07', '04:14', '04:19', '04:34', '04:49', '05:05', '05:20', '05:35', '06:05', '06:15', '06:22', '06:29', '06:37', '06:44', '06:52', '06:59', '07:06', '07:12', '07:17', '07:23', '07:28', '07:33', '07:38', '07:43', '07:49', '07:55', '08:01', '08:06', '08:12', '08:18', '08:25', '08:32', '08:40', '08:47', '08:54', '08:59', '09:14', '09:29', '09:44', '09:59', '10:14', '10:45', '10:54', '11:02', '11:09', '11:16', '11:24']
